d164c609e7 ethdev: add eCPRI key fields to flow API
Add a new item "rte_flow_item_ecpri" in order to match eCRPI header.

eCPRI is a packet based protocol used in the fronthaul interface of
5G networks. Header format definition could be found in the
specification via the link below:
https://www.gigalight.com/downloads/standards/ecpri-specification.pdf

eCPRI message can be over Ethernet layer (.1Q supported also) or over
UDP layer. Message header formats are the same in these two variants.

9da82e8d8b mbuf: introduce accurate packet Tx scheduling
There is the requirement on some networks for precise traffic timing
management. The ability to send (and, generally speaking, receive)
the packets at the very precisely specified moment of time provides
the opportunity to support the connections with Time Division
Multiplexing using the contemporary general purpose NIC without involving
an auxiliary hardware. For example, the supporting of O-RAN Fronthaul
interface is one of the promising features for potentially usage of the
precise time management for the egress packets.

The main objective of this patchset is to specify the way how applications
can provide the moment of time at what the packet transmission must be
started and to describe in preliminary the supporting this feature
from mlx5 PMD side [1].

The new dynamic timestamp field is proposed, it provides some timing
information, the units and time references (initial phase) are not
explicitly defined but are maintained always the same for a given port.
Some devices allow to query rte_eth_read_clock() that will return
the current device timestamp. The dynamic timestamp flag tells whether
the field contains actual timestamp value. For the packets being sent
this value can be used by PMD to schedule packet sending.

The device clock is opaque entity, the units and frequency are
vendor specific and might depend on hardware capabilities and
configurations. If might (or not) be synchronized with real time
via PTP, might (or not) be synchronous with CPU clock (for example
if NIC and CPU share the same clock source there might be no
any drift between the NIC and CPU clocks), etc.

After PKT_RX_TIMESTAMP flag and fixed timestamp field supposed
deprecation and obsoleting, these dynamic flag and field might be
used to manage the timestamps on receiving datapath as well. Having
the dedicated flags for Rx/Tx timestamps allows applications not
to perform explicit flags reset on forwarding and not to promote
received timestamps to the transmitting datapath by default.
The static PKT_RX_TIMESTAMP is considered as candidate to become
the dynamic flag and this move should be discussed.

When PMD sees the "rte_dynfield_timestamp" set on the packet being sent
it tries to synchronize the time of packet appearing on the wire with
the specified packet timestamp. If the specified one is in the past it
should be ignored, if one is in the distant future it should be capped
with some reasonable value (in range of seconds). These specific cases
("too late" and "distant future") can be optionally reported via
device xstats to assist applications to detect the time-related
problems.

There is no any packet reordering according timestamps is supposed,
neither within packet burst, nor between packets, it is an entirely
application responsibility to generate packets and its timestamps
in desired order. The timestamps can be put only in the first packet
in the burst providing the entire burst scheduling.

PMD reports the ability to synchronize packet sending on timestamp
with new offload flag:

This is palliative and might be replaced with new eth_dev API
about reporting/managing the supported dynamic flags and its related
features. This API would break ABI compatibility and can't be introduced
at the moment, so is postponed to 20.11.

For testing purposes it is proposed to update testpmd "txonly"
forwarding mode routine. With this update testpmd application generates
the packets and sets the dynamic timestamps according to specified time
pattern if it sees the "rte_dynfield_timestamp" is registered.

The new testpmd command is proposed to configure sending pattern:

set tx_times <burst_gap>,<intra_gap>

<intra_gap> - the delay between the packets within the burst
              specified in the device clock units. The number
              of packets in the burst is defined by txburst parameter

<burst_gap> - the delay between the bursts in the device clock units

As the result the bursts of packet will be transmitted with specific
delays between the packets within the burst and specific delay between
the bursts. The rte_eth_read_clock is supposed to be engaged to get the
current device clock value and provide the reference for the timestamps.

50ce3e7aec ethdev: fix VLAN offloads set if no relative capabilities
Currently, there is a potential problem that calling the API function
rte_eth_dev_set_vlan_offload to start VLAN hardware offloads which the
driver does not support. If the PMD driver does not support certain VLAN
hardware offloads and does not check for it, the hardware setting will
not change, but the VLAN offloads in dev->data->dev_conf.rxmode.offloads
will be turned on.

It is supposed to check the hardware capabilities to decide whether the
relative callback needs to be called just like the behavior in the API
function named rte_eth_dev_configure. And it is also needed to cleanup
duplicated checks which are done in some PMDs. Also, note that it is
behaviour change for some PMDs which simply ignore (with error/warning
log message) unsupported VLAN offloads, but now it will fail.

36fbaaf30d ethdev: fix data room size verification in Rx queue setup
In the rte_eth_rx_queue_setup API function, the local variable named
mbp_buf_size, which is the data room size of the input parameter mp,
is checked to guarantee that each memory chunk used for net device
in the mbuf is bigger than the min_rx_bufsize. But if mbp_buf_size is
less than RTE_PKTMBUF_HEADROOM, the value of the following  statement
will be a large number since the mbp_buf_size is a unsigned value.
    mbp_buf_size - RTE_PKTMBUF_HEADROOM
As a result, it will cause a segment fault in this situation.

This patch fixes it by modify the check condition to guarantee that the
local variable named mbp_buf_size is bigger than RTE_PKTMBUF_HEADROOM.

6b30428820 doc: refine ethernet and VLAN flow rule items
Specified pattern may be translated in different manner.
For example the pattern "eth / ipv4" can be translated to match
untagged packets only, since the pattern doesn't specify a VLAN item.
It can also be translated to match both tagged and untagged packets,
for the same reason.
This patch updates the rte_flow documentation to clearly specify the
required pattern to use.
For example:
To match tagged ipv4 packets, the pattern "eth / vlan / ipv4 / end"
should be used.
To match untagged ipv4 packets, the pattern "eth / ipv4 / end"
should be used.
To match all IPV4 packets, both tagged and untagged, need to apply
two rules with the patterns above.
To match both tagged and untagged packets of any type, the pattern
"eth / end" should be used.

eeb486f3ba eal: add telemetry as dependency
This patch moves telemetry further down the build, and adds it as a
dependency for EAL. Telemetry V2 is now configured to build by default,
and the legacy support is built when the telemetry config flag is set.

Telemetry now has EAL flags, shown below:
"--telemetry" = Enables telemetry (this is default if no flags given)
"--no-telemetry" = Disables telemetry

When telemetry is enabled, it will attempt to open the new socket
version, and also the legacy support socket (this will depend on Jansson
external dependency and telemetry config flag, as before).

44bf3c796b ethdev: support flow aging
One of the reasons to destroy a flow is the fact that no packet matches
the flow for "timeout" time.
For example, when TCP\UDP sessions are suddenly closed.

Currently, there is not any DPDK mechanism for flow aging and the
applications use their own ways to detect and destroy aged-out flows.

The flow aging implementation need include:
- A new rte_flow action: RTE_FLOW_ACTION_TYPE_AGE to set the timeout and
  the application flow context for each flow.
- A new ethdev event: RTE_ETH_EVENT_FLOW_AGED for the driver to report
  that there are new aged-out flows.
- A new rte_flow API: rte_flow_get_aged_flows to get the aged-out flows
  contexts from the port.
- Support input flow aging command line in Testpmd.

The new event type addition in the enum is flagged as an ABI breakage,
so an ignore rule is added for these reasons:
- It is not changing value of existing types (except MAX)
- The new value is not used by existing API if the event is not
  registered
In general, it is safe adding new ethdev event types at the end of the
enum, because of event callback registration mechanism.

725e515ed1 ethdev: allow multiple security sessions to use flow rule
The rte_security API which enables inline protocol/crypto feature
mandates that for every security session an rte_flow is created. This
would internally translate to a rule in the hardware which would do
packet classification.

In rte_security, one SA would be one security session. And if an rte_flow
need to be created for every session, the number of SAs supported by an
inline implementation would be limited by the number of rte_flows the
PMD would be able to support.

If the fields SPI & IP addresses are allowed to be a range, then this
limitation can be overcome. Multiple flows will be able to use one rule

conf would be NULL.

Application should do an rte_flow_validate() to make sure the flow is
supported on the PMD.

2e02a2afff ethdev: fix VLAN offloads set if no driver callback
Currently, there is a potential problem that changing the content of
dev->data->dev_conf.rxmode.offloads even when there is no
vlan_offload_set driver callback.

It is a good idea that prevent the side effect and make the API return
success if no change requested. This patch fixes the problem, the detail
information as below:
 - keep possibility to do dummy set even if there is no driver callback
 - do not touch Rx mode offloads in device data before checking the
   driver callback availability
 - ensure that Rx mode offloads are rolled back correctly if driver
   callback returns error

since the queue arrays are limited to RTE_MAX_QUEUES_PER_PORT.

The advertised capabilities of mlx4, mlx5 and softnic
for the number of queues were the maximum number: UINT16_MAX.
They must be limited by the configured RTE_MAX_QUEUES_PER_PORT
that applications expect to be respected.

The limitation is applied at ethdev level (function rte_eth_dev_info_get),
in order to force the configured limit for all drivers.

64edb05e29 ethdev: fix item expansion for RSS flow
When the last item in flow pattern includes "next protocol" field which
is relevant for RSS flow expansion, a new item is added to the pattern
according to the "next protocol" field. This field is called missed
field.

The missed field wrongly was not initialized what caused to some of the
flow item fields to contain garbage values.

As a result, the PMDs internal flow engine may crash.

For example, the spec value may include garbage pointer and to cause
crash.

Initialize the missed field with zeroes.

fbaf943887 build: remove individual library versions
Since the library versioning for both stable and experimental ABI's is
now managed globally, the LIBABIVER and version variables no longer
serve any useful purpose, and can be removed.

The replacement in Makefiles was done using the following regex:

	^(#.*\n)?LIBABIVER\s*:=\s*\d+\n(\s*\n)?

(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

The replacement for meson files was done using the following regex:

	^(#.*\n)?version\s*=\s*\d+\n(\s*\n)?

(version = numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

[David]: those variables are manually removed for the files:
- drivers/common/qat/Makefile
- lib/librte_eal/meson.build
[David]: the LIBABIVER is restored for the external ethtool example
library.

eccc5d3237 ethdev: fix last item detection on RSS flow expand
There is a rte_flow API which expands a RSS flow pattern to multiple
patterns according to the RSS hash types in the RSS action
configuration.

As part of the expansion, detection of the last item of the flow uses
the "next proto" field of the last configured item in the pattern list.
Wrongly, the mask of this field was not considered in order to validate
the field.

Ignore "next proto" fields when their corresponded masks invalidate them.
